Summary
enough与too的用法
enough和too二者均用于描述程度，语义相反。
enough表示足够的/地，程度刚好满足需求。
too表示太/过于，程度超出可接受范围。
均可修饰形容词/副词，enough还可修饰名词，too无此用法。
enough的用法
enough修饰形容词/副词，放在其后；修饰名词，放在其前。
口诀：名前形副后，enough的位置记心头。
e.g. She is tall enough to reach the shelf. 形后：tall是形容词，enough后置
He runs fast enough to catch up. 副后：fast是副词，enough后置
We have enough water for the trip. 名前：water是名词，enough前置
There are enough chairs for everyone. 名前：chairs是名词，enough前置
too的用法
too仅能修饰形容词/副词，放在其前；无修饰名词的用法，可与副词much/many连用：too much water
口诀：too修饰形和副，一律放在前面住。
e.g. The bag is too heavy to carry. 形前：heavy是形容词，too前置
He talks too quickly to understand. 副前：quickly是副词，too前置
Don't drive too fast on the road. 副前：fast是副词，too前置
It is too cold to go out today. 形前：cold是形容词，too前置

Practice
Amy is writing about the dining hall plete her sentences with enough or too.
I don’t have enough books at home, so I often visit the community library. When I sit at the reading table, I keep my personal items tidy enough for others to use the shared space. A library requires a quiet atmosphere, so we shouldn’t make too much noise. If we have to answer a call, we mustn’t talk too loudly; our voice should be soft enough or low enough not to disturb others. When browsing books, we should handle them gently enough to help preserve them for future readers.
Write some sentences to discuss good manners in the library, using enough and too.
Read the text and pay attention to the use of enough to and too ... to.
Read and summarise
In many countries, people are patient enough to wait in line in banks and shops. Also, they are kind enough to hold the door for you when you go in or out of a building. In public places, people are polite enough to keep their voices down.
In many countries, people are too polite to jump the line in banks and shops. Also they are too kind to push past you when you are in their way. In public places, people are thoughtful enough to keep quiet.
We usually use enough to and too ... to like this:
be patient enough to wait in line
kind hold the door for you
polite keep their voices down
thoughtful keep quiet
be too polite to jump the line
kind push past you
Enough to means there is as much as needed, so something _____________ (can, cannot) happen. The word enough comes _____________ (before, after) an adjective.
Too... to means there is more than what is necessary, so something _____________ (can, cannot) happen. The word too comes _____________ (before, after) an adjective.
can

cannot

In the structures above, we can add “for someone” before the to-infinitive.
e.g. The food is too hot for Robert to enjoy.
Summary
enough to和too…to的用法
enough to和too…to结构核心为形/副 + 不定式（to do），用简单句表达“程度导致的结果”，两大结构语义一肯一否。
“be + adj./adv. + enough to do 足够……去做某事”，表肯定结果，表示主语具备的特征，足以完成后续动作，结构中to后接动词原形，无人称变化。
e.g. He is strong enough to lift the box.
他足够强壮，能举起这个箱子。
She studies hard enough to pass the exam.
她学习足够努力，能通过考试。
“be + too + adj./adv. + to do 太……而不能做某事”，表否定结果，表示主语的特征程度过甚，导致动作无法完成，结构本身含否定含义，无需额外加not，to后接动词原形，为不定式的基本形式。
e.g. She is too weak to carry the bag. 她太虚弱了，提不动这个包
It's too late to catch the early bus. 太晚了，赶不上早班车了
too…to形容词描述事物时，后可加for sb.明确动作对象，结构变为too + adj. + for sb. + to do，用于说明“对某人而言，太……而不能做某事”，突出动作的主体，让语义更具体明确，避免因动作对象模糊导致的句意歧义。
e.g. The book is too hard for her to read. 这本书对她而言，太难读了。
The question is too easy for me to answer.
这个问题对我而言，太容易回答了
enough to表肯定，强调“能够做某事”；too…to表否定，强调“不能做某事”；二者核心均为形/副+to do，结构相近；根据语境确定语义的肯否；可替换句式。
e.g. He is tall enough to reach the top.
他够高，能够到顶端（肯定）
He is too short to reach the top.
他太矮，够不到顶端（否定）
She is rich enough to buy the watch.
她够有钱，能买下这块手表（肯定）
She is too poor to buy the watch.
她太穷，买不起这块手表（否定）

The library is a place for study and research. It is important to be quiet enough to avoid disturbing others in the library. Some people talk too loudly, which makes it difficult for students to concentrate. Also, avoid making noise in the library. This can make it too difficult for people to focus on their work or studies. A library is a shared space, so we should all be respectful enough to clean up after ourselves. Treat books with enough care. Always wash your hands before handling books.
